Thanks Bob, I had an inkling it would be something like that when I saw Gene's post on Page 6&7-friendly modules.

Now, for some reason, I can't get (Lib4),OSX, Zenrom and HEPAX_8H installed all at once, I get a BAD CONFIG error, regardless of the OSX rom that I use.

When I have Lib4, HEPAX_8H and Zenrom, the Rom map looks like

Pg 6 HEPAX_8H
Pg 7 Free
Pg8;9;A;B HEPAX RAM
Pg C Zenrom

So it looks like the PG7 version of OSX would fit? But it doesn't. Nor does the 'normal' one.

Cheers, Werner

OS/X and ZENROM both use ROM ID 05, so the conflict is unrelated to the port which OS/X uses. Yes, it's frustrating as I too consider OS/X to be a fundamental part of any serious 41 configuration I use, and would be great to have it, even if I want to use ZENROM.

One feasible solution is to change (via some hex editor) the ROM ID byte of the ZENROM image you load, but that would make it custom and programs which use ZENROM Fns would not be portable. But if only used interactively this would be OK, and likely have no side-effects. To consider this, verify the ROM IDs of all the modules you plan to use in this configuration and pick an unused one. It's easy to see the ROM ID in the 41X's Module ROM Map, at the left edge of the Modules by Page column.
